Copying Files To Flash Memory; Making A Flash Memory Card Image Bootable - Cisco 7500 Series Configuration Manual

Chapter 4 Performing a Basic Configuration of the System

Copying Files to Flash Memory

You might need to copy a new image file to Flash memory whenever a new Cisco IOS software release
or maintenance release becomes available.
Caution You cannot copy a new image into Flash memory while the system is running from Flash memory.
We recommend that you upgrade Cisco IOS software images in Flash memory one at a time; do not
delete all known-good images at one time. Also, upgrade PC Card-based Flash memory separately from
onboard Flash memory, to avoid losing important Cisco IOS software images that are known to be good.
(The onboard Flash memory is referred to as the bootflash.)
Use the command copy tftp:filename [bootflash | slot0 | slot1]: filename for the copy procedure, where
tftp:filename is the source of the file and [ bootflash | slot0 | slot1]: filename is the destination in
onboard Flash memory or on either of the Flash memory cards.
An example of the copy tftp:filename command follows for a file in the Flash memory card in PC Card
slot 0:
Router# copy tftp:myfile1 slot0:myfile1
20575008 bytes available on device slot0, proceed? [confirm]
Address or name of remote host [10.1.1.1]?
Loading new.image from 10.1.1.1 (via Ethernet1/0): !!

In the preceding example, the exclamation points (!!!) appear as the file is downloaded, and the "C"
Note
characters signify calculation of the checksum, which is a verification that the file has been correctly
downloaded to the Flash memory card.

Making a Flash Memory Card Image Bootable

Use the following series of commands to make a Flash memory card image bootable. (In this example,
the filename is new.image.) Note that the config-register command is part of the sequence because the
configuration register must be set to 0x2102 to enable loading an image from Flash memory.
Router# config terminal
Router(config)# no boot system
Router(config)# boot system flash slot0:new.image
Router(config)# config-register 0x2102
Crtl-Z
Router# copy running-config startup-config
Router# reload
When the system reloads, it will boot the image new.image from the Flash memory card in slot 0.
